Modular Circuit Protection

MCBs, RCBOs, RCCBs, Add-on Block, Busbars and Connectors, SPDs and Fuses

Our range of Modular Protection Devices (MPDs) offer high quality and practical solutions and options for protecting electrical circuits, people, equipment and property. We offer a wide range of MPDs such as Miniature Circuit Breakers (MCB), Residual Current Breaker with overcurrent protection (RCBO), Residual Current Circuit Breaker (RCCB) and Surge Protection Devices (SPD). A range of accessories are also available including busbars, auxiliary contacts and relays.

Miniature Circuit Breakers (MCBs)

For general distribution loads, our MSNxxx Miniature Circuit Breaker (MCB) range short circuit and overcurrent protection of installations by isolating the circuit.

Residual Current Circuit Breakers with Overcurrent Protection (RCBOs)

Hager RCBOs are suitable for many types of installation and can be used in our DIN rail enclosures and Paneboards.

Residual Current Circuit Breaker (RCCBs / RCDs) - Safety Switches

Residual Current Circuit Breaker (RCCB) or ‘Safety Switches’ are designed to open a protected circuit automatically when the circuit leaks current to earth, greater or equal to the devices rated tripping current.

One Module Add On Blocks (AOB)

Our single module wide RCD Add-On Block (AOB) is designed to convert any Hager three module MCB up to 63A into a four module wide RCBO. This can save up to 40% of space in the commercial and light industrial applications.

Busbars and Connectors

A range of connection devices to simplify installation of modular protection devices.

Surge Protection Devices (SPDs)

Our Surge Protection Devices protect electrical and electronic equipment against transients originating from lightning and switching sources. These transients can cause premature aging of equipment, logic failures and down time, to the complete destruction of electrical components.
