1SDA018951R1 ABB SACE Isomax S6N 800 PR211-LI In=800A 3P FF MCCB

Product Overview:  ABB 1SDA018951R1

Parameter Specification
Manufacturer ABB 
Order Number 1SDA018951R1
Model Code S6N 800 PR211-LI R800 3P F F
Product Type Moulded Case Circuit Breaker (MCCB), power distribution type

Application & Fault Scenarios

  • Typical Uses: The S6N 800 PR211-LI serves as an incomer or feeder breaker in LV main switchboards, distribution boards, generator output panels, capacitor bank feeders, and industrial plant substations where an 800 A circuit with 35 kA breaking capacity at 400 V is required. The PR211-LI electronic trip unit provides adjustable overload and instantaneous short-circuit protection, making it suitable for general distribution networks without earth-fault protection requirements. It also replaces failed units in existing Isomax S installations where maintaining the original footprint and wiring is necessary.
    Common Field Issues:
    • Breaker trips instantly on load → check whether the instantaneous I setting is too low for motor starting/inrush current; raise the I threshold or add a time-delay stage (requires PR212-LSI upgrade).
    • Breaker will not close / handle blocked → mechanism may be in tripped position; push handle fully to OFF (reset) then close. Also check for an energised shunt opening release or open undervoltage release circuit.
    • Trip unit shows no indication / no response → PR211-LI may require minimum current or auxiliary supply to operate; verify wiring of the trip unit supply and test with the built-in test button if fitted.
    • Overheating at terminals → check cable lug torque, contact surface oxidation and phase current balance; an unbalanced load on one pole causes localised heating.

FAQ

Q1: What does "S6N 800 PR211-LI 3P F F" mean?
A: S6 = frame size (630–800 A); N = breaking capacity class (Icu 35 kA @380/415 V); 800 = rated current 800 A; PR211-LI = electronic trip unit with overload (L) and instantaneous short-circuit (I) protection; 3P = three poles; F F = fixed mounting with front terminals.
Q2: What is the breaking capacity of 1SDA018951R1?
A: Icu = 35 kA at 380/415 V AC for the S6N 800. If your installation requires a higher short-circuit withstand (e.g., close to a large transformer), choose the S6S (50 kA) or S6H (65 kA) version instead.
Q3: Does PR211-LI provide earth-fault protection?
A: No. PR211-LI offers only two-stage protection: long-time overload (L) and instantaneous short-circuit (I). For earth-fault/ground-fault protection you need PR212-LSIG or an external residual-current relay.
