GE HEA61A223X2

  • Product Name: GE HEA61A223X2 125 V DC 3‑stage lock‑out (trip‑control) relay.
  • Product Overview: A heavy‑duty, three‑stage lock‑out relay (not a breaker itself) that works with GE HEA‑series air‑circuit‑breaker control circuits to latch a trip command, prevent accidental re‑closing, and provide alarm/lock‑out signaling for protection‑relay schemes.

Detailed content

  • Technical Specifications:
    • Coil voltage: 125 V DC (nominal, ≈ 23 Ω coil resistance)
    • Contact configuration: 3 independent stages (SPST, each stage with NO/NC)
    • Contact rating: 10 A @ 125 V DC / 250 V AC (resistive)
    • Mechanical life: ≥ 1 000 000 operations
    • Electrical life: ≥ 100 000 operations at rated load
    • Operating temperature: –10 °C to +50 °C
    • Standards: UL, CSA, IEC 60255
    • Dimensions: ≈ 3.9″ × 2.9″ × 1.9″; weight ≈ 1.5 lb
  • Functional Features: Positive mechanical lock‑out after a trip; manual reset button; three independent contacts allow trip command, alarm output, and lock‑out signal upload; suitable for HEA‑series ACB trip circuits and protection interlocks.
  • Application Scenarios: Power‑plant and heavy‑industrial control panels; protection‑relay lock‑out; anti‑re‑closing schemes for air‑circuit breakers; motor‑control and safety‑interlock systems.
  • Material & Structure: Phenolic‑resin flame‑retardant base (UL 94 V‑0); silver‑alloy (AgCdO) contacts; enameled‑copper coil; steel armature with spring return; transparent dust cover with manual reset lever.
  • Working Principle: On a DC‑coil energization, the relay latches mechanically and opens/closes the three contact sets; once tripped, the relay stays locked until an operator manually resets the lever, thereby blocking unintended breaker re‑closure.
  • Installation Requirements: Panel or DIN‑rail mounting inside a low‑voltage switch‑gear or relay panel; wire the 125 V DC coil from the protection‑relay output; connect the three contact sets according to the lock‑out logic; ensure proper screw‑terminal torque.
  • Usage Precautions: High‑voltage DC terminals – install and service only by qualified electricians; follow LOTO; verify coil voltage is 125 V DC (not AC); after a trip, manually reset only after the fault condition is cleared; keep the environment within –10 °C to +50 °C and below 95 % RH (non‑condensing).
