General Purpose Relay MJN 341
General Purpose Relay
MJN
Relay with Plug-in Termination, available
in SPDT, DPDT or 3PDT models
• Rugged power driver offers superior 3/16” through-air
and 3/8 over-surface spacing
• Interlocked frame and contact block prevent contact
misalignment during plug-in
• Available with dust covers, indicator lamps and
push-to-operate buttons
• UL and CSA recognition as motor controllers up to 600 VAC
• Recognized for 1/2 hp motor control applications at 240/
480/600 VAC (1/3 hp at 120 VAC)
