Schleicher IPA 1 Relay K617 866 60min 500W 380V 6A Relay

Schleicher IPA 1 Relay, variant code K617 866, is a time-delay switching relay that provides a defined delay before energizing or de-energizing a connected load. It specifies a 60-minute timing interval and supports a 500 W load at 380 V with a 6 A contact rating, enabling reliable control of moderate-power circuits in electrical panels and automation panels. As part of Schleicher’s family of timing relays, the IPA 1 is designed for simple integration into control architectures where a precise delay improves sequencing, prevents nuisance startups, or coordinates auxiliary devices in automated equipment. In practice, time-delay relays like this are commonly used to sequence fans, pumps, signaling devices, or indicator circuits, offering a compact, single-component solution to implement repetitive or single-shot delay behaviors without external timers.
