The Schurter Inc. 4435.0478 is a 1-pole thermal circuit breaker with a rocker actuation type, suitable for panel mounting. It offers a rated AC voltage of 240 VAC (IEC) and 277 VAC (UL/CSA), with a DC rating of 32 VDC. The current rating range is from 0.05 to 20 A, with this specific model rated at 16A.
This circuit breaker has a conditional short circuit capacity of 2 kA at 240 VAC. It provides an IP40 degree of protection on the front side. The dielectric strength is greater than 2.5 kV at 50 Hz and greater than 4 kV for impulse 1.2/50 μs. Insulation resistance is over 100 MΩ at 500 VDC.
Mechanical lifetime is rated for 50,000 switching cycles. Electrical lifetime is 30,000 cycles at AC (cos φ 0.6) and 50,000 cycles at DC (L/R = 2-3 ms). Overload performance 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.
Operating temperature ranges from -30 °C to 60 °C, with storage temperatures from -40 °C to 60 °C. It meets vibration resistance standards according to IEC 60068-2-6 and shock resistance standards according to IEC 60068-2-27. The tripping type is thermal.
