Schneider Electric A9N61525 is an Acti9 C60H‑DC miniature circuit breaker designed for DC distribution circuits where dependable protection against overloads and short-circuits is required. This 2‑pole, thermal‑magnetic MCB features a C tripping curve and a 5 A rated current (at 25 °C), making it well suited to protecting smaller DC feeders and control circuits while maintaining robust fault-clearing performance.
Rated for up to 500 V DC, the A9N61525 offers high breaking capacities across common DC voltages, including up to 20 kA at 250 V DC and 6 kA at 500 V DC (IEC/EN 60947‑2). It mounts onto a 35 mm symmetrical DIN rail and provides clear local ON/OFF indication via the toggle mechanism. The device is suitable for isolation and includes provision for padlocking in the OFF position to support lockout procedures during maintenance.
Built for panel environments, it is specified for operation from −25 to +70 °C (storage −40 to +85 °C), pollution degree 3, and overvoltage category IV. Standard top or bottom connections and compatibility with comb busbars/distribution blocks help simplify installation in compact DC distribution assemblies.

What type of device is this?
It is a two-pole miniature circuit-breaker (MCB) designed for DC distribution circuits, using a thermal-magnetic trip mechanism to protect against overloads and short-circuits.
What does “2-pole” mean for this breaker?
Two-pole means it switches and protects two conductors together, providing simultaneous disconnection across both poles for DC circuits.
What is the rated current?
The rated current is 5 A at 25 °C.
What is the rated operational voltage for DC applications?
The rated operational voltage is 500 V DC.
What does a C-curve trip characteristic mean?
A C-curve MCB is intended for circuits with moderate inrush currents, where brief start-up surges may occur without representing a fault, while still providing rapid protection during short-circuits.
What are the short-circuit breaking capacity ratings (Icu)?
The ultimate breaking capacity (Icu) includes 20 kA at 250 V DC, 20 kA at 220 V DC, 10 kA at 440 V DC, and 6 kA at 500 V DC (per IEC/EN 60947-2, with additional GB 14048.2 ratings stated for 220/250 V DC).
What is the service breaking capacity (Ics) at common DC voltages?
The rated service breaking capacity (Ics) is stated as 75% of Icu: 15 kA at 220 V DC, 15 kA at 250 V DC, 7.5 kA at 440 V DC, and 4.5 kA at 500 V DC (IEC/EN 60947-2).
Is it suitable for isolation?
Yes. It is stated as suitable for isolation in accordance with IEC 60947-2 and EN 60947-2.
What mounting method does it use?
It is designed for fixed mounting on a 35 mm symmetrical DIN rail.
Can it be used with comb busbars or distribution blocks?
Yes. It is compatible with standard comb busbars and distribution blocks, top or bottom, with 9 mm pitch (4 modules).
Does it provide earth-leakage (residual current) protection?
No. This device is specified as “without” earth-leakage protection; it provides overcurrent and short-circuit protection only.
What is the tightening torque for power terminals?
The specified tightening torque for the power circuit terminals is 2.5 N·m (top or bottom).
Can the handle be padlocked in the OFF position?
Yes. It is padlockable, with locking described in position O (OFF).
What operating and storage temperature ranges are specified?
Ambient air temperature for operation is -25 to +70 °C, and ambient air temperature for storage is -40 to +85 °C.
What standards is it built to?
It is specified to EN 60947-2 and IEC 60947-2.
What mechanical and electrical endurance is specified?
Mechanical durability is specified as 20,000 cycles. Electrical durability is specified as 3,000 cycles (L/R = 2 ms) in the product data. This device is commonly referenced as Schneider A9N61525.
What is the pollution degree and overvoltage category?
It is specified for pollution degree 3 and overvoltage category IV.
What is the approximate weight and colour?
Net weight is approximately 0.256 kg, and the unit is white.
