This Schurter Inc. 4430.351 is a thermal circuit breaker with a 2-pole configuration, suitable for various industrial applications. It features a rocker actuation type and a panel mount design for easy integration into equipment.
The circuit breaker has a rated AC voltage of 240 VAC and a rated DC voltage of 60 VDC. The rated current range is from 0.05A to 20A AC. It provides thermal overload protection with a positively trip-free release mechanism.
Key technical specifications include a conditional short circuit capacity of 1 kA at 240 VAC and various Icn ratings depending on current and voltage conditions. The device offers a degree of protection of IP40 on the front side, which can be increased to IP54 with a factory-mounted protection cover. It has a dielectric strength of 4 kVAC and an insulation resistance greater than 100 MΩ at 500 VDC.
Mechanical lifetime is rated at 50,000 switching cycles, with AC and DC operational lifetimes also at 50,000 cycles at 1x Ir. Overload performance includes a minimum of 40 trips at 6x Ir for AC and 4x Ir for DC. The operating temperature range is -10 °C to 55 °C, with storage temperature also within this range. The circuit breaker is resistant to vibration and shock according to IEC standards.
The circuit breaker is rated for 240 VAC and 60 VDC.
