Key Specifications General Manufacturer: ABB Model / Part Number: CT‑ARE / 1SVR550127R4100 Product Type: Electronic time delay relay (OFF‑delay) Timing Function: True OFF‑delay (delay on break) Series: CT‑E timer series Mounting: DIN rail mount (TH35‑7.5 or TH35‑15) Terminal Type: Screw terminals Housing Width: ~22.5 mm Dimensions (approx): 22.5 mm (W) × 78 mm (H) × 78.5 mm (D) Weight: ~0.07 kg Operating Temperature: –20 °C to +60 °C (typical) Protection Rating: ~IP20 (front and terminals) LED Controls +1 Control / Supply Rated Control Supply Voltage (Us): 24 V AC/DC 220 – 240 V AC (50/60 Hz) The device supports multiple supply ranges so it can be used in lower voltage DC/AC circuits or mains AC control circuits. LED Controls Timing Adjustable Time Range: 0.3 s to 30 s (adjustable via front‑panel dial) Timing Function Description: When supply voltage is removed, the relay remains energized and delays switching off for the set time period. LED Controls Output Contact Configuration: 1 change‑over contact (SPDT / 1 c/o) Rated Operational Current: AC‑12: 4 A @ 230 V AC AC‑15: 3 A @ 230 V AC DC‑12: 4 A @ 24 V DC DC‑13: 2 A @ 24 V DC Contact Voltage Rating: up to 250 V AC These ratings make it suitable for controlling small contactor coils, indicator lights, and control circuits. LED Controls +1 Standards & Compliance Designed to comply with relevant IEC/EN timer relay standards (e.g., IEC/EN 61812‑1) UL 508, CAN/CSA C22.2 and other regional safety certifications RoHS compliant environmental standards
