The Schurter Inc. 4430.3652 is a 2-pole thermal circuit breaker with a panel mount type and rocker actuation. It provides a rated current of 20A and operates at a voltage of 240 VAC and 60 VDC.
Key electrical specifications include a conditional short circuit capacity of 1 kA (AC 240V) and various short circuit capacities (Icn) depending on the current rating and voltage. The breaker is designed for thermal tripping and offers a mechanical lifetime of 50,000 switching cycles.
Environmental and mechanical data include a degree of protection of IP40 on the front side, a dielectric strength of 4 kVAC, and an insulation resistance greater than 100 MΩ at 500 VDC. The operating temperature range is -10 °C to 55 °C.
This circuit breaker is suitable for applications requiring reliable thermal overload protection. Its robust construction and adherence to standards like IEC 60934 and UL1077 make it a dependable choice for industrial and equipment applications.
The 4430.3652 is rated for 240 VAC and 60 VDC.
The allowable operating temperature range is -10°C to 55°C.
The breaker has a conditional short circuit capacity of 1 kA at 240VAC (IEC 60934 PC1). Under specific test conditions, the short circuit capacity Icn is: for currents <3A at 240VAC or 60VDC, 10xIn (max 3 cycles); for currents ≥3A at 240VAC, 300A; for currents ≥3A at 48VDC, 120A.
The 4430.3652 is a 2-pole circuit breaker.
The front side offers IP40 protection according to IEC 60529. With the factory-mounted protection cover, it is rated IP54.
The breaker is approved under CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077.
The mechanical and electrical lifetime is 50,000 switching cycles under nominal load.
