The Schurter Inc. 4400.002 is a thermal circuit breaker designed for equipment protection. This 1-pole device features a snap-in mounting type and quick connect terminals for easy installation.
Key electrical specifications include a rated voltage of 240 VAC and 48 VDC, with a rated current range of 0.05 to 16 A. It has a conditional short circuit capacity of 2 kA at 240 VAC and an Icn of 8 x In or 96 A depending on the current rating.
This circuit breaker operates within a temperature range of -5 °C to 60 °C and offers a degree of protection of IP40 on the front side. It is built to withstand vibration and shock according to IEC standards.
Applications for this thermal circuit breaker include power tools, household equipment, power supplies and chargers, and industrial appliances. It is approved by CSA, EN, GB, IEC, and UL standards.
The circuit breaker is rated for 240VAC and 48VDC.
The allowable operating temperature is -5°C to 60°C.
The circuit breaker is panel mounted with quick connect terminals (6.3 x 0.8 mm).
For In < 6.5A at 240VAC, Icn is 8 times the rated current (8 x In).
The dielectric strength is >1.5kV at 50Hz and >2.5kV impulse (1.2/50μs).
The insulation resistance is >100 MΩ at 500VDC.
The typical endurance is 500 switching cycles at 2 times the rated current.
