2 Pole, 40 Amp

Type CH for use in Cutler Hammer load centers

Requires two 3/4-inch spaces

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.

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.

· Function: This circuit breaker can protect the amplifier from being damaged by the over-load current or voltage. Meanwhile, the power supply can also be protected to avoid battery crack and explosion caused by short circuit.

· Specification: Voltage 12-48V DC, compatible with all 12V/24V Systems. Ambient temperature: -32 ° c to 82 ° c (-25 ° f to 180 ° f) ，Accessories added wire lugs and Copper washer.

· Manual Reset Circuit Breaker, Use in place of an inline fuse holder, the unique push button reset can also be used as a Kill Switch.
