OEMs and panel builders need a simple clock to cycle a fan, pump, sign or refrigeration defrost without a programmable controller. The Intermatic FM1STUZH-120U is a 24-hour electromechanical timer module that mounts inside a control panel or equipment housing, with a 21 A SPDT contact and a 120 VAC synchronous motor. Captive trippers set in 15-minute steps, and the H in the part number means it has a built-in manual override switch.
Why panel builders pick it
- Compact 2.36 x 2.36 x 1.25 in module fits tight control panels.
- 21 A SPDT contact switches a load on or off, or changes over between two circuits.
- Captive trippers can't fall out and get lost, with 15-minute resolution.
- Manual override switch for service and testing.
- 1/4 in quick-connect terminals for fast panel wiring.

Pro tip from the counter
In a dusty or oily control cabinet, order the DC-FME-A clear cover with the module. It is sold separately, and without it grit settles on the dial and a stray tool or finger can knock trippers off their setting during service.
Best for: OEM control panels, refrigeration defrost and merchandiser cases, ventilation fans, septic and aeration pumps, sign and landscape lighting panels
