ABB YO-1SDA038292R1 YC-1SDA038302R1 Product Description

Overview

ABB YO-1SDA038292R1 YC-1SDA038302R1 is an ABB SACE breaker release coil accessory set for low-voltage air or molded case circuit breakers. The reference pair combines the YO release, part number 1SDA038292R1, with the YC release, part number 1SDA038302R1. In ABB SACE breaker accessory naming, YO identifies a shunt opening or shunt release function, while YC identifies a closing or shunt closing release coil. Distributor data lists the coil supply as 220 to 240 V, covering AC or DC control supply for the matched breaker application. The release coils are mounted on the breaker to provide remote electrical tripping or closing operation in switchgear, motor control centers and control panels.

Features

ABB YO-1SDA038292R1 and YC-1SDA038302R1 are breaker-mounted electromagnetic release coils for ABB SACE circuit breakers. The YO coil provides shunt opening release: when energized from an external control command, it releases the breaker trip mechanism to open the circuit breaker. The YC coil provides closing or shunt closing operation: it drives the breaker closing mechanism for electrical closing from a remote control, PLC output, protection relay or switchboard control circuit.

Distributor product records describe the pair as a shunt closing and opening release coil for low-voltage power breakers, with a supply voltage of 220/240 V DC/AC according to one automation supplier listing. The coil assembly weight is listed at approximately 0.698 kg in distributor stock data. The exact compatible breaker frame, terminal wiring, coil duty and contact configuration must be matched to the original ABB SACE breaker manual and accessory drawing; public distributor listings do not provide the full ABB datasheet details for these exact part numbers.

Principle

ABB YO-1SDA038292R1 and YC-1SDA038302R1 operate as electromagnetic release mechanisms integrated with the ABB SACE breaker. The YO shunt release receives a control voltage command from a protection relay, PLC, emergency stop circuit, switchboard control or remote trip signal. When energized, the coil pulls its internal armature, which mechanically releases the breaker trip mechanism and opens the circuit breaker to isolate the protected circuit.

The YC closing coil receives a closing command and drives the breaker closing mechanism to close the breaker electrically, typically where manual closing is impractical or remote control is required. The coil supply voltage and control circuit rating must match the breaker accessory specification; incorrect voltage, coil function or wiring can prevent reliable tripping, closing or breaker status operation. Because these are breaker-mounted accessories, replacement should match the original ABB SACE breaker frame, coil part numbers, terminal arrangement and control wiring shown in the breaker manual or spare-part drawing.

Applications

ABB YO-1SDA038292R1 YC-1SDA038302R1 is used in ABB SACE breaker installations requiring remote shunt trip, electrical closing, emergency shutdown, protection relay tripping, PLC or DCS-based breaker control, and switchgear monitoring in industrial panels, motor control centers, distribution boards, power systems, utilities, water and wastewater, chemical and process plants, pulp and paper, marine switchgear, commercial buildings and equipment manufacturer panels. In existing ABB breaker installations originally equipped with these release coils, the pair serves as a direct replacement accessory spare, compatible with the original breaker mounting, control terminals and wiring arrangement.
