Small rectangular relay with metal terminals and plastic housing

Value Brand

Value Brand Potential Relay 35A 450V AC

SKU CH-FCHE-3Z5DA

A potential relay rated 35 A at 450 V AC with pick-up between 189 V and 205 V and drop-out at 130 V AC

  • Reliable switching for HVAC systems
  • 35 amp contact rating handles heavy loads
  • Operates at 450V AC coil voltage
  • Precise engagement between 189V and 205V AC
  • Safe dropout at 130V AC maximum

Relay purpose

The Value Brand potential relay is a mechanical SPST device rated for 35 amps at 450 volts AC. It suits HVAC technicians and maintenance engineers who need a reliable switching component for motor-start circuits in air-conditioning or refrigeration equipment.

Voltage thresholds

The relay picks up between 189 and 205 volts AC and drops out at a maximum of 130 volts AC. These fixed thresholds mean the unit cannot be adjusted for non-standard control voltages, so installers must verify that the system operates within this window before fitting.

Contact rating

The 35-amp contact rating at 450 volts AC is the single specification that determines whether this relay can handle the intended load. Circuits drawing more current or operating at a higher voltage will exceed the device limits and require a different part.

Questions about this item

How often should the mechanical contacts be inspected or replaced on this 35 A potential relay?

The SPST mechanical contacts are rated for 35 amps at 450 V AC; inspect them during routine HVAC maintenance and replace if pitting or sticking appears.

What voltage limit stops the relay from picking up during sustained operation?

The coil requires at least 189 V AC to pick up and will not energise below that level; the maximum pick-up threshold is 205 V AC.

How much heat does the coil generate when it stays energised at 450 V AC all day?

The coil is designed for continuous 450 V AC operation; normal warmth is expected, but excessive heat suggests voltage outside the 189–205 V AC pick-up range.
