Limit electrical risks caused by earth leakages with this residual current circuit breaker from ABB. The 4-pole unit automatically trips the power when people or objects touch live wires. By detecting AC and pulsing DC faults, it offers inclusive protection. Its compact dimensions of 70 (W) x 85 (H) x 69mm (D) save space on distribution boards, while a modular design simplifies multi-component assemblies. As it simply clips onto a DIN rail, installation is convenient and tool-free.

• Easy-to-flip toggle switch for quick resetting
• Light weight of 360g unit puts minimal strain on equipment
• Hardwearing plastic housing protects against impacts and contamination

• Industrial electrical installations
• Domestic appliances
• Lighting systems

You should match the trip sensitivity and current rating with your specific needs. For example, 30mA is sensitive and may disrupt power supplies without any apparent faults, making it suitable in places where people are in constant contact with equipment. This unit has 300mA tripping sensitivity, which can be used with circuits powering industrial machinery.
