What type of electrical device is this?

It is a ComPact NS1600N circuit breaker basic frame designed for low-voltage AC power distribution. The unit has four poles, a fixed mounting arrangement and manual operation.

What is the rated current of this circuit breaker frame?

The rated current is 1,600 A at an ambient temperature of 50°C.

Does this unit include a trip unit?

No. Schneider 33264 is supplied as a basic circuit breaker frame without a trip unit. A compatible protection arrangement must therefore be selected separately for the intended installation.

How many poles does the circuit breaker have?

This model has four poles, with the neutral pole positioned on the left.

What is the rated operational voltage?

The rated operational voltage is up to 690 V AC at 50 or 60 Hz.

What is its short-circuit breaking capacity at 415 V AC?

The rated ultimate short-circuit breaking capacity is 50 kA at 380/415 V AC. Its N performance level is designated as 50 kA at 415 V AC.

How does the breaking capacity vary by operating voltage?

The rated ultimate breaking capacity is 85 kA at 220/240 V AC, 50 kA at 380/415 V AC, 50 kA at 440 V AC, 40 kA at 500/525 V AC and 30 kA at 660/690 V AC.

Is this circuit breaker suitable for isolation?

Yes. It is suitable for isolation in accordance with EN/IEC 60947-2.

How is the device operated?

The circuit breaker is manually operated using its rotary handle and toggle mechanism.

Is this a fixed or withdrawable circuit breaker?

It is a fixed-mounting circuit breaker intended for installation on a backplate.

What are the dimensions of the unit?

The circuit breaker frame measures approximately 327 mm high, 280 mm wide and 147 mm deep. The connection pitch is 70 mm.

What environmental protection ratings does it have?

The device is rated IP40 in accordance with IEC 60529 and IK07 in accordance with EN 50102. It is also classified for pollution degree 3 under IEC 60947.

What operating temperatures can it withstand?

The specified ambient operating temperature range is -25°C to 70°C. The storage temperature range is -50°C to 85°C.

What are the insulation and impulse withstand ratings?

The rated insulation voltage is 800 V AC, and the rated impulse withstand voltage is 8 kV, both specified in accordance with IEC 60947-2.

What is the short-time withstand current?

The rated short-time withstand current is 19.2 kA for one second in accordance with IEC 60947-2.

What mechanical and electrical endurance does the unit offer?

The specified mechanical endurance is 10,000 operating cycles. Electrical endurance varies with voltage and load, including 2,000 cycles at 440 V AC at rated current and 1,000 cycles at 690 V AC at rated current.

How much power does the circuit breaker dissipate?

The stated power loss for the circuit breaker frame is 74 W.

Which standard does this model comply with?

The circuit breaker is specified as conforming to IEC 60947-2, the standard covering low-voltage circuit breakers.

What applications is this circuit breaker frame intended for?

It is intended for low-voltage AC distribution applications requiring a four-pole, 1,600 A fixed circuit breaker frame with manual operation and high fault-current interruption capability.

What should be checked when selecting compatible components?

Confirm the required trip unit, electrical ratings, four-pole configuration, fixed mounting format, neutral position, connection pitch and installation dimensions. Compatibility should be assessed against the complete switchboard design and protection requirements.
