Schrack RT78725 Latching Relay 16A 12VDC Atlas Type
Schrack RT78725 Atlas Latching Relay – 16 A, 12 V DC Coil
The Schrack RT78725 is a DIN-rail-mount latching (bistable) relay rated at 16 A / 250 V AC on its primary switching group and 8 A / 250 V AC on its secondary group. Designed under TE Connectivity’s Atlas series, the relay holds its switched position without continuous coil power, making it ideal for energy-saving control circuits in pool automation panels, irrigation controllers, greenhouse climate systems, and general industrial switching.
The relay operates from a 12 V DC coil pulse and covers an ambient temperature range of −20 °C to +70 °C, ensuring reliable year-round performance in outdoor pump houses or heated glasshouses. The integrated test/override button (red actuator visible on the coil module) allows manual operation during commissioning without a live control signal. Socket-mount construction means the relay module separates cleanly from its base for fast field replacement without disturbing wiring.

Compatibilidade
The RT78725 is pin-compatible with the standard Schrack RT78 socket footprint. It is suited for use in pool pump control panels, automated irrigation valve switching, and greenhouse heating or ventilation circuits wherever a bistable (no-power-hold) switching function is required. Verify coil voltage (12 V DC) and socket model against your panel design before ordering.

Em detalhe
- Latching design retains switch state with zero continuous coil power — reduces energy consumption in always-on control panels
- Dual contact ratings (16 A and 8 A) allow control of both high-load pump circuits and auxiliary signals from a single relay
- Socket-mount base enables tool-free relay replacement without rewiring
- Manual test button (red) speeds commissioning and fault-finding
- Wide temperature range (−20 °C to +70 °C) suits outdoor pump-house and greenhouse enclosures
- Bistable operation requires a pulse-capable controller — not suitable for simple on/off coil drive without a bistable output module
- 12 V DC coil only; not interchangeable with 24 V DC or AC coil variants without changing the relay module
- No labeled dimensional data (DN, thread, mm) — this is an electrical relay, not a pipe fitting; no fluid-path compatibility applies
