Manufactured in China

Frequently used for AC or DC Branch circuits

Meets American Boat and Yacht Council (ABYC) standards

The industry standard circuit breaker for Blue Sea Systems" electrical panels

SQU QO120 1P 20AMP 120/240V CIRCUIT BREAKER

FUNCTIONS: Used to protect power distribution facilities from overload and short-circuit damage, and can also be used for control and isolation.

FAST TRIP: The electromagnetic trip system can trip immediately when the circuit is short-circuited to protect the safety of the circuit.

ARC EXTINGUISHING: DC arc extinguishing is more difficult than AC. This DC mini circuit breaker has a magnetic system to assist arc extinguishing.

Ideal for Automotive / Industrial / Marine And Others Applications DIY

Compact design enables high density circuit protection configurations

Push-to-Reset Operation,with a waterproof button clear cap to protect from bad weather

Product Name: Manual Reset 125-250V AC 50V DC Push Button Switch Thermal Circuit Breaker.

Operating Voltage: 125/250V AC 50V DC; power rating: 20A (amp).Operating Temperature: -10oC (14oF) to 60oC (140oF) Interrupt Capacity:1,000 Amps

Working Principle: this switch can be reset after a disconnect over a period of time, then you can press the reset switch to use it again When load exceeds rated current, the switch reset button will automatically cut off the circuit, and thus play a role in protecting the line.
