Design Of The Productfor motor protection

Product details

It is rated for a continuous current of 0.2 A and trips in CLASS 10, meaning it will clear a stalled-rotor overload within 10 seconds at 7.2× rated current — fast enough to protect small motors without nuisance tripping on normal starts. Breaking capacity sits at 100 kA across the board — at 240 V, 400 V, 500 V, and 690 V AC — so it handles high-fault-current panels without cascading upstream. The 690 V rated insulation voltage matches the maximum circuit voltage in many industrial motor branches.

Depth is 96 mm, so check enclosure depth if you're retrofitting into a shallow gland box. Solid wire accepts 2× (0.5…1.5 mm²) and 2× (0.75…2.5 mm²); stranded accepts 2× (1…2.5 mm²) and 2× (2.5…6 mm²). AWG for main contacts is 2× (14…10). The auxiliary switch is transverse design and the product extension supports adding auxiliary switches. IP20 on the front — sealed against fingers but not dust or washdown.

Shock rated at 25g / 11 ms. Substance prohibitance date is 01.05.2012 — RoHS compliance is implied for that EU effective date.
