Protect your electrical circuits from overloads with this miniature circuit breaker from ABB. This safety component has two tripping mechanisms – a delayed thermal system for overload protection and an electromechanical tripping device for short-circuit shielding. It works by cutting power to the circuit when a fault occurs before it can cause damage to your equipment. You can easily reset it after clearing the fault with a toggle actuator switch. For impact and abrasion resistance, the breaker has a thermoplastic housing, making it suitable for use in harsh environments. You'll find components like this useful in low-voltage applications like domestic distribution boards and network switches.

• Light weight of 250g so it's easy to handle and won't strain your DIN rail
• Can be connected to either conductors or a bus bar for versatility
• DIN rail mounting style is easy and tool-less, saving time and effort
• Red and green status indicators to easily show contact position

• Power transmission and distribution systems
• Automation and robotics

This circuit breaker can last up to 20,000 operating cycles, so you can rely on it for long-term performance.
