You can also search for a Competitor Cross Reference to find a drop-in equivalent 88H Series relay.


Contact Transfer LED Indicator
LED is not wired to coil like traditional relays, providing positive confirmation of contact transfer unlike legacy hermetically sealed relays.

Hermetically Sealed Construction
The inert, dry nitrogen environment mitigates corrosion and/or oxidation of the internal relay components including the contacts.

Coil
Coil Temperature Rating 155 °C (Class F) Optional coil suppression diode that will protect your sensitive equipment from coil transient voltage.

Corrosion Resistant
  • Nickel Plated Brass Cover
  • Salt water Resistant
