The Schurter Inc. 4400.0215 is a thermal circuit breaker with a compact design and positively trip-free release. It is a 1-pole, reset-type breaker with quick connect terminals, suitable for panel mounting.
This circuit 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 an Icn of 8 x In or 96 A depending on the rated current. The degree of protection on the front side is IP40.
Key electrical specifications include a dielectric strength greater than 1.5 kV (50 Hz) and 2.5 kV (1.2/50 μs impulse), and an insulation resistance greater than 100 MΩ at 500 VDC. Endurance is rated typically at 500 switching cycles and a minimum of 50 switching cycles under specific DC conditions. Overload endurance meets IEC standards with a minimum of 40 trips at 6 x Ir and UL/CSA standards with a minimum of 50 trips at 1.5 x Ir.
The operating temperature range is -5 °C to 60 °C. Mechanical specifications include vibration resistance up to 5 G and shock resistance of 100 G / 6 ms. The breaker has a weight of approximately 10 g. It is designed according to product standards such as IEC 60934 and UL 1077, and holds approvals from VDE, UL, and CCC.
The circuit breaker is rated for 240 VAC and 48 VDC.
