4P Compact Full Circuit Breakers (up to 630A)

Industrial Protection & Control: Efficiency and Safety

Henvi’s industrial protection and control range has been designed to provide complete control over the electrical and mechanical systems within your infrastructure. As specialist distributors, we bring together in a single catalogue the essential components to ensure that your industrial operation is not only productive, but also resilient to failures and safe for all operators.

Control Components for Precise Automation

Industrial control is the brain of any electrical panel. At Henvi, we supply devices that enable direct interaction between people and machines, as well as the automatic control of loads:

• Power Contactors: For starting and stopping motors and large loads.
• Push Buttons and Signalling Devices: Control buttons, emergency stops and indicator lights for local control.
• Control Relays: For auxiliary logic and thermal protection of equipment.

Industrial Protection Against Electrical Faults

To protect your most valuable assets, Henvi selects protection devices that respond quickly to abnormal operating conditions:

Motor Protection: Motor circuit breakers and thermal overload relays that prevent damage caused by overloads or phase failure.

Technical Selectivity: Ensuring that only the affected area is isolated, keeping the rest of the installation operational.

Durability: Equipment designed to withstand intensive switching cycles in factory environments.

The Ideal Partner for Control and Protection Projects

At Henvi, we understand the challenges faced by maintenance technicians. That is why we offer more than electrical equipment: we provide technical specification support. Whether you need to size a starting system for a pump or configure a control console, our team ensures that you receive the right components, with the necessary European certifications and immediate stock availability.

Frequently Asked Questions About Protection & Control

What does industrial protection and control cover?

This area encompasses all devices that control the flow of energy (control, such as contactors and push buttons) and those that protect equipment and people against electrical faults (protection, such as motor circuit breakers and relays).

What is the importance of integrating protection and control in the same panel?

Integration allows the control system to monitor the status of the protection system. For example, if a motor overheats, the protection device can send a signal to the control system to stop operation and indicate the fault with a warning light, preventing further damage.

Are Henvi control devices compatible with automation systems?

Yes. Our contactors and control devices are compatible with industrial standards, allowing integration with PLCs (programmable logic controllers) and other centralised technical management systems through universal coils and auxiliary contacts.

Moulded Case Circuit Breakers (MCCBs) up to 630A

Moulded case circuit breakers (MCCBs) up to 630A are essential solutions for protecting electrical circuits in large-scale installations and high-current applications. Their efficiency, robustness and ease of installation make them an ideal choice for industrial, commercial and building installations, providing reliable protection against electrical faults. In addition, the wide range of types and functions available allows these circuit breakers to be used in different applications, ensuring safety and continuity of power supply.

High-Performance Protection for Electrical Panels

MCCBs are designed to withstand high short-circuit currents, ensuring that a fault in one branch does not compromise the entire infrastructure. Thanks to their moulded case construction, they provide superior insulation and mechanical durability suitable for frequent switching operations.

Key features of our range:

• Precise Adjustment: Adjustable thermal and magnetic trip units for enhanced selectivity.
• Versatility: Available in three-pole (3P) and four-pole (4P) versions.
• Safety: High breaking capacity (kA) suitable for transformer substations and main electrical panels.

Applications of Moulded Case Circuit Breakers

Given their versatility and current ratings of up to 630A, these devices are the ideal choice for:

• Protection of incoming feeders in main low-voltage switchboards (LVMDPs).
• Switching and protection of high-power electric motors.
• Installations in industrial environments with demanding thermal conditions.
• Critical power systems where fast tripping is essential.

Why Choose Henvi for Your Switching Protection?

At Henvi, we provide more than just components; we offer technical support to help you choose the MCCB with the appropriate tripping characteristics and breaking capacity for your project. With stock availability and fast delivery, we are a strategic partner for installers who cannot afford unplanned downtime on their projects.

Frequently Asked Questions About MCCB Circuit Breakers

What is the difference between a modular circuit breaker and an MCCB?

The main difference lies in current capacity and robustness. While modular circuit breakers are used for final circuits (generally up to 125A), moulded case circuit breakers (MCCBs) support much higher currents (up to 630A at Henvi) and allow tripping parameters to be adjusted, providing greater precision in industrial environments.

What does adjustability mean in an MCCB?

Many MCCBs allow the rated current limit (Ir) to be adjusted. This means that a 250A circuit breaker can, for example, be set to trip at 200A, allowing the protection to be adapted to the actual installed load without replacing the equipment.

How do I choose the breaking capacity (kA) for a circuit breaker up to 630A?

The breaking capacity must be higher than the prospective short-circuit current at the installation point. In electrical panels located close to transformer substations, MCCBs with breaking capacities of 36kA, 50kA or higher are commonly required.

Can these circuit breakers be used with accessories?

Yes. Our range of MCCBs is compatible with various accessories, including auxiliary signalling contacts, shunt trip coils and motorised operators for electrical panel automation.
