GENERAL PURPOSE RELAY TYPE 157 TYPE 157 FEATURES: • The Type 157 relay is a rugged power driver offering superior 3/16” through air and 3/8” over-surface spacing. • An interlocked frame and contact block prevent contact misalignment during plug-in. • Open or dust covered available with indicator lamps and push-to-operate buttons. • A magnetic latching version provides a unique switchable core which cannot be falsely latched. • All Midtex catalog Type 157 relays have UL & CSA Recognition as motor controllers through 600 VAC • They provide through air spacing of 3/16” minimum and over-surface spacing of 3/8” minimum and are recognized for 1/2 hp motor controller applications at 240/480/600 VAC (1/3 hp at 120 VAC). • Chassis mounted open relays must employ 1/32” additional insulation between mounting surface and relay to insure 1/2” over-surface and through air to the mounting surface. • Sockets for the 157 relays are constructed to meet UL requirements for these ratings. • UL File E38802 CSA LR54109 CONTACTS -100 -200 -300 -700 -3MO 1/8” Fine Sliver (gold flash) 5 amp 3/16” Silver Cadmium Oxide 10 amp COILS UL & CSA Recognition Rating Voltage Ratings 5 amp, 28 VDC/ 120/240 VAC, 80% pf 2 amp 480/600 VAC, 80% pf 1/8 hp 120 VAC 1/4 hp 240 VAC 2 amp 7.2 amp in rush, 24 VAC (SP devices) Pick-up Voltage Material 10 amp, 28 VDC/ 1/3 hp 1/2 hp 36 LRA, 3 amp 10 amp 120/240 VAC, 80% pf 120 VAC 277/240/480/600 VAC 8.5 FLA, 18VDC 480/600 VAC, 80% pf 277VAC resistive 15 amp 10 amp 3 amp 1/3 hp 1/2 hp 600w Tungsten 1/8” Fine Sliver Gold Diffused 5 amp, 28 VDC/ 120/240 VAC, 80% pf 2 amp 480/600 VAC, 80% pf 1/8 hp 120 VAC 1/4 hp 240 VAC 2 amp 7.2 amp in rush, 24 VAC (SP devices) (See Note) 1 Form X 2 Form A 2 Form C Shock 277/240/120 VAC 28 VDC 480/600 VAC 120 VAC 240/480/600 VAC 120/240 VAC AC–85% of nominal DC–75% of nominal Rated for continuous duty operation at 25% overvoltage 15 g’s, 11±1mS (non-operating test, no mechanical damage) 0.1” DA or 10g’s, 10 to 55 Hz (operating test, no contact chatter) Vibration Power Ratings* 1 & 2 Pole AC 3 Pole AC DC 1.7 VA 2.7 VA 2.0 VA 3.1 VA 1.2 W 1.9 W Nominal Max.
