Description:

Wheelock Series MPS non-coded Manual Pull Stations are
constructed of high quality, die-cast metal for long lasting
performance and may be mounted on a single gang backbox.

Available in either single or dual action configurations for
indoor or outdoor use with SPST contacts and terminal strip
connections. The normally open contact will close when the
pull station is activated and is rated for 30 VDC @ 1 amp and/or
120 VAC @ 1 amp. The contacts are gold plated to avoid the
risk of corrosion.

The single action explosion-proof model Series MPS-400X is UL
Listed and Factory Mutual approved for use in Class I, Division

NEMA-3R listed when mounted to the MPS-WP weatherproof
back box.

All models are painted red with raised white lettering and a
locking mechanism to prevent unauthorized reset.
