WTH8-25 Household Modular Contactor 25A
The WTH8-25 is the 25A size of the WTH8 modular range, a coil operated contactor for DIN rail mounting. It carries 25A in AC-1 and AC-7a duty with 5kW at 230V and 16kW at 400V, which covers lighting circuits and small distribution feeders.
Current Ratings
AC-1 and AC-7a rating is 25A with a thermal current of 25A. Motor duty, AC-3 and AC-7b, is rated 9A with 1.2kW at 230V and 4kW at 400V.
Coil Operation
Operation is by coil only, which separates this model from the WTH8-25M that adds a manual lever. Rated insulation voltage is 500V, and operating voltage is 250V for two pole and 400V for four pole versions.
Module Width and Mounting
The 2 pole body is 18mm wide and the 4 pole body 36mm, both 85mm long and 66.5mm high, so a 4 pole unit takes two modules on the rail.
