Key Features Time Delay Function: Adds an adjustable electronic delay before breaker opening on undervoltage or specified trigger. Compatible with Multiple Breaker Series: Fits a range of ABB breakers including the Tmax XT and Emax families. AC/DC Supply: Designed to operate on a 220 – 250 V AC/DC coil or control voltage. Accessory Module: Used as an add‑on to extend protective functionality of circuit breakers. Compact Design: Sized to integrate with breaker accessories in panel installations. DIN/Panel Friendly: Dimensions and mounting suit standard electrical enclosure layouts. Electrical Ratings Rated Control Supply Voltage: 220 – 250 V AC/DC — works with both AC and DC control supplies. Input Type: Designed for AC and DC voltage sensing used in timing logic. Timing Function: Electronic delay between voltage condition and release action (helps avoid unwanted trips). Integration: Works with other breaker control accessories to coordinate undervoltage and delayed release behavior. Mechanical & Environmental Module Width: Approximately 150 mm. Height: Approximately 60 mm. Depth: Approximately 200 mm. Weight: Around 0.25 kg. Installation: Connected as an accessory to compatible breakers; panel or accessory rail mounting typical. Ambient Conditions: Suitable for standard industrial panel environments. Functional Use This electronic time delay unit is used to delay breaker opening in response to certain voltage conditions, reducing the chance of unnecessary trips during short disturbances. For example, in motor control centers or distribution panels, it helps maintain continuity through transient dips, while still providing protective action if the condition persists. Typical Applications Low‑voltage power distribution panels where transient voltage drops are common. Motor control and feeder circuits requiring controlled undervoltage response. Industrial automation systems needing enhanced coordination between supply conditions and breaker operation. Enhancing protective functionality of ABB Tmax and Emax circuit breakers by adding timing logic.
