Schneider Electric RE17RBMU Time Delay Relay Spdt 8A

Product Description

The SCHNEIDER ELECTRIC RE17RBMU is a multiple-range, interval-function time delay relay rated for 8 amps with a single-pole double-throw (SPDT) contact form. It accepts a supply voltage of 24 VDC or 24 to 240 VAC, making it compatible with a wide range of control circuits. Timing is set via a selector switch, with a minimum delay of 0.1 seconds and a maximum delay of 100 hours across multiple selectable ranges. The unit mounts on standard DIN rail and is designed to be installed by licensed electricians or industrial control technicians in panel-build and automation applications.

This relay is used in residential, commercial, and light industrial control panels where programmable interval timing is required. Typical applications include motor start sequencing, lighting control circuits, HVAC interlock timing, and process automation. The selector-switch adjustment method allows field technicians to change timing ranges without additional tools, making it well suited to service-and-replace scenarios as well as original equipment installation.

Key Features

• Interval timer function with multiple selectable timing ranges from 0.1 seconds to 100 hours
• SPDT contact form rated at 8 amps for broad load compatibility
• Dual-voltage input: 24 VDC and 24 to 240 VAC on a single unit
• DIN rail mount for fast, tool-friendly panel installation
• Selector switch timing adjustment — no potentiometer trimming required
• Meets CE, cULus (File E173076), CSA (File 248382), IEC 61812-1, GL, and RoHS requirements

Compatibility

Designed as an OEM-style replacement or new-installation time delay relay for standard DIN rail control panels requiring SPDT interval timing with multi-range selector adjustment.

Installation Notes

Installation should be performed by a qualified electrician in accordance with applicable NEC requirements and local codes. De-energize and lock out the control panel before handling relay wiring or seating the unit on the DIN rail. Verify supply voltage matches the circuit before energizing. Confirm the selected timing range on the selector switch before commissioning the circuit.
