| Design Of The Product | for motor protection |
Continuous rated current is 0.32 A with Trip Class CLASS 10.
IP20 protection on the front means it is finger-safe for panel installation but not rated for washdown environments. Wire sizes: solid conductors accept 2x (0.5…1.5 mm²) and 2x (0.75…2.5 mm²); stranded accept 2x (1…2.5 mm²) and 2x (2.5…6 mm²); AWG for main contacts is 2x (14…10).
Shock resistance rated at 25g for 11 ms. Substance prohibitance (RoHS compliance) dated 01.05.2012.
Yes, it includes phase failure detection; it does not include ground fault detection.
