NF32-SV2P5A Molded Case Circuit Breaker NF32SV2P5A 2P 5A Amp 200V AC Brand New
NF32-SV2P5A | Mitsubishi NF-S Series WS-V MCCB
2-Pole / 5A / 30AF / 600V / 8kV / Low-Voltage Circuit Protection
MCCB — More Than an On/Off Switch
A Moulded Case Circuit Breaker is the primary protective device in low-voltage power distribution circuits. Unlike a simple switch or isolator, the MCCB combines three functions in one compact unit:
  • Circuit isolation: Manual on/off switching for equipment isolation during maintenance and commissioning.
  • Overload protection: The MCCB's thermal element detects sustained overcurrent — motor overloads, equipment starting longer than expected, or slowly developing faults — and trips the breaker before wiring or equipment insulation is damaged by heat.
  • Short-circuit protection: The magnetic trip element reacts instantaneously to the high fault current of a short circuit — clearing the fault within milliseconds to protect both the circuit and other loads on the same distribution bus.
The NF32-SV2P5A provides all three in a moulded case that fits standard distribution panel mounting.

2-Pole Configuration — Right for Single-Phase and DC Applications
The NF32-SV2P5A's 2-pole (2P2d) configuration interrupts both circuit conductors simultaneously — both the phase and neutral in single-phase circuits, or both positive and negative in DC circuits. Two-pole MCCBs are the standard choice for:
  • Single-phase sub-circuit protection in 240V distribution panels
  • Control transformer output protection (phase and neutral interruption)
  • 24VDC or 48VDC circuit protection where both poles must be isolated for safety
  • Motor branch circuits where a 2-pole disconnect is required by wiring regulations
Application Scenarios
Automation panel branch circuit protection: A control panel supplying 5A to a field device (a small drive, a valve pack, or an instrumentation supply) is protected by the NF32-SV2P5A. If the field device develops a fault, the breaker trips and isolates the branch without disturbing other circuits in the panel.
Machine tool control transformer protection: The 240V output of a control transformer supplying the machine's 24V PSU chain is protected by the NF32-SV2P5A on the secondary side — providing both overload and short-circuit protection for the transformer's output circuit.
Frequently Asked Questions
Q1: What is the difference between "30AF" and "5AT" in the NF32-SV2P5A description?
AF (Ampere Frame) and AT (Ampere Trip) are two distinct ratings. AF refers to the maximum current the breaker's frame, bus connections, and contacts can physically carry and interrupt — the NF32-SV2P5A's 30AF frame is physically rated for 30A. AT refers to the calibrated trip setting — the current level at which the thermal and magnetic elements will trip. The 5AT setting means the NF32-SV2P5A protects a 5A circuit. Both ratings are needed to fully specify an MCCB.
Q2: Can the NF32-SV2P5A be used on DC circuits as well as AC?
Mitsubishi NF-S series MCCBs are primarily rated for AC applications. DC circuit breakers require specific arc interruption capability since DC arcs do not self-extinguish at current zero crossings the way AC arcs do. If a DC application is planned, confirm from the Mitsubishi NF-S series data sheet whether the NF32-SV2P5A is DC-rated and at what DC voltage the rating applies. Do not assume AC-rated MCCBs are suitable for DC applications without this confirmation.
Q3: How does the thermal trip in the NF32-SV2P5A work?
The thermal element is a bimetallic strip in series with the circuit. Sustained current above the 5A trip rating heats the bimetal, causing it to deflect. When deflection reaches the trip threshold, the mechanism releases and the breaker opens. This response is intentionally time-delayed — it allows brief overloads (motor starting current, inrush) to pass without nuisance tripping while responding to sustained overloads that indicate a real fault.
Q4: What tools are required to reset the NF32-SV2P5A after a trip?
No tools are required. After a trip, the handle moves to an intermediate position between ON and OFF, indicating a tripped state. To reset, move the handle fully to the OFF position (to reset the mechanism), then back to ON. Before resetting, confirm the fault cause has been identified and corrected — resetting a breaker onto an uncleared fault will cause an immediate re-trip.
Q5: Can the trip rating of NF32-SV2P5A be adjusted in the field?
The NF32-SV2P5A is a fixed trip unit with a 5AT setting — the trip current is factory-set at 5A and cannot be field-adjusted. Some larger MCCB families offer adjustable thermal and magnetic trip settings through dial or slide adjusters on the front face, but the NF-S standard frame series uses fixed trip units matched to the rated current specified in the ordering code.
