Product Summary

The GRT508HA is a 100A two-pole latching relay designed for smart energy metering and prepaid meter circuits. It uses AgSnO2 contacts and requires only impulse excitation to switch and hold state, so the coil does not need continuous power. The relay is TUV UC3 compliant and supports custom assemblies with flexible wire, copper straps or an integrated shunt.

Key Features

• 100A two-pole switching: Two sets of contacts support 100A resistive load with 250VAC maximum switching voltage.
• Impulse excitation only: Single and double coil versions hold state without continuous coil power.
• 4KV dielectric strength: Coil-to-contact isolation supports metering safety requirements.
• UC3 and RoHS compliance: TUV UC3 certification and RoHS compliance suit EU metering projects.
• Low coil power, compact body: 100A load capability in a 70 x 52 x 21.9 mm outline.
• Custom assembly options: Flexible wire, copper strap and integrated shunt builds are available.
