1SDA073725R1 ABB Spring Charging Motor (M) for Emax 2 Air Circuit Breakers E2.2…E6.2, 220-250V AC/DC

Product Overview: ABB 1SDA073725R1

Parameter Specification
Manufacturer ABB 
Order Number 1SDA073725R1
Product Type Spring Charging Motor (M) for air circuit breaker mechanism
Application Charges the closing springs of ABB Emax 2 low-voltage ACB after each closing operation, enabling automatic re-close readiness

Application & Fault Scenarios

  • Typical Uses: The 1SDA073725R1 is the spring charging motor (M) used on ABB Emax 2 air circuit breakers in frames E2.2, E4.2 and E6.2. It automatically rewinds the closing springs after each operation so the breaker is ready for the next close or auto-reclose cycle. Widely used in LV main incomer and bus-tie applications: switchboards, generator sets, UPS input/output panels, data centres, marine switchboards, industrial plants and building main distribution.
    Common Field Issues:
    • Breaker shows "springs not charged" and will not close → check that control voltage 220-250V AC/DC is present at the motor terminals; inspect the fuse/MCB in the control circuit; listen for motor hum. If silent, suspect open winding or burnt motor.
    • Motor runs continuously without stopping → mechanical linkage or limit-switch fault in the charging mechanism; stop operation immediately to avoid motor burnout and gear damage.
    • Motor runs but springs do not charge / abnormal noise → worn gears, broken pawl or insufficient lubrication in the operating mechanism; inspect the mechanism compartment.
    • Motor burns out repeatedly → check for undervoltage operation, excessive close-open cycles, or incorrect voltage rating (e.g., replacing a 110V unit with this 220-250V type).

FAQ

Q1: What is ABB 1SDA073725R1?
A: It is the spring charging motor (M) for ABB Emax 2 low-voltage air circuit breakers, frames E2.2 to E6.2, rated 220-250V AC/DC. It automatically re-charges the closing springs after each operation.
Q2: Which breakers is 1SDA073725R1 compatible with?
A: Emax 2 frames E2.2, E4.2 and E6.2. It does not fit E1.2 (use 1SDA073711R1) and is not compatible with Tmax XT MCCBs or VD4 medium-voltage breakers. Verify the nameplate voltage before fitting.
Q3: Symptoms of a failed charging motor?
A: "Springs not charged" indication, breaker refuses to close, no sound when control power is applied, burning smell, or motor running continuously without stopping. In the last case, isolate power immediately and check the mechanism linkage.
