4400.0495

The Schurter Inc. 4400.0495 is a thermal circuit breaker designed for equipment protection. This 1-pole breaker features a snap-in version with quick connect terminals (6.3 x 0.8 mm) and a push-to-reset actuation type.

Key electrical specifications include a rated AC voltage of 240 VAC and a rated DC voltage of 48 VDC. The rated current range is from 0.05 to 16 A, with a specific rating of 2.5A for this model. It offers a conditional short circuit capacity of 2 kA (AC 240V) and a short circuit capacity Icn of 8 x In (for In < 6.5 A) or 96 A (for In ≥ 6.5 A).

Environmental and mechanical features include a degree of protection of IP40, dielectric strength greater than 1.5 kV (50 Hz) and 2.5 kV (1.2/50 μs impulse), and insulation resistance greater than 100 MΩ at 500 VDC. The operating temperature range is -5 °C to 60 °C. Endurance is rated typically at 500 switching cycles and a minimum of 50 switching cycles for reset types. Overload testing per IEC standards requires a minimum of 40 trips at 6 x Ir, and per UL/CSA standards, a minimum of 50 trips at 1.5 x Ir.

This circuit breaker is suitable for applications such as power tools, household equipment, power supplies and chargers, and industrial appliances. It has approvals from CSA, EN, GB, IEC, and UL.
