The Schurter Inc. 4400.0184 is a thermal circuit breaker designed for equipment protection. It features a compact, drop-in type design with a panel mount and push-to-reset actuation.
This single-pole breaker operates at a rated voltage of 240 VAC and 48 VDC, with a rated current range of 0.05 to 16 A. It offers a conditional short circuit capacity of 2 kA at 240 VAC and a short circuit capacity (Icn) of 8 A or 96 A depending on the rated current. The front side provides an IP40 degree of protection.
Key electrical specifications include a dielectric strength greater than 1.5 kV at 50 Hz and 2.5 kV impulse, and an insulation resistance greater than 100 MΩ at 500 VDC. Endurance is rated for a typical 500 switching cycles at 2x Ir, and a minimum of 50 switching cycles for reset types. Overload testing shows a minimum of 40 trips at 6x Ir for IEC standards and 50 trips at 1.5x Ir for UL/CSA standards.
Suitable for applications such as power tools, household equipment, power supplies and chargers, and industrial appliances, this circuit breaker operates within a temperature range of -5 °C to 60 °C. It has undergone vibration resistance testing up to 5 G and shock resistance testing of 100 G / 6 ms.
The rated voltage is 240 VAC and 48 VDC.
The allowable operating temperature range is -5 °C to 60 °C.
The rated current range AC is 0.05 to 16 A.
It uses panel mount with quick connect terminals.
The front side has IP40 protection according to IEC 60529.
The conditional short circuit capacity is 2 kA at 240 VAC.
