Schneider Electric ComPact NS800H MCCB – 800A – 70kA – Micrologic 2.0 – 3P Fixed (Ref 33467)

Schneider Electric ComPact NS800H MCCB (33467) Overview

The Schneider Electric ComPact NS800H, catalogue reference 33467, is an 800A moulded-case circuit breaker (MCCB) with a 70kA breaking capacity at 415VAC and a Micrologic 2.0 electronic trip unit. It is a 3-pole, fixed, manually operated device used for main-incomer and feeder protection in low-voltage switchboards, distribution boards, and motor-control centres. The Micrologic 2.0 control unit provides adjustable long-time and instantaneous protection for reliable overload and short-circuit coverage on three-phase installations.

Quick Specs

• Catalogue reference 33467, Schneider Electric ComPact NS range (NS630b to NS1600).
• Device type is a moulded-case circuit breaker (MCCB).
• Rated current In is 800A, set by the Micrologic 2.0 control unit.
• Breaking capacity Icu is 70kA rms at 415VAC, the H performance class.
• Rated operational voltage Ue is 690VAC at 50/60 Hz.
• Trip unit is Micrologic 2.0, giving adjustable long-time and instantaneous (LI) protection, ANSI 49 and 50.
• Configuration is 3 poles, 3d (all three poles protected and tripped).
• Mounting is fixed and the breaker is manually operated with ON, OFF, and push-to-trip.
• Conforms to IEC 60947-1 and IEC 60947-2.
• Mechanical durability is up to 10,000 operating cycles.

Applications & Compatibility

The NS800H is selected on both its 800A rating and its 70kA breaking capacity, which must match the prospective short-circuit current at its point of installation. As a Micrologic 2.0 (LI) device, it suits standard overload and short-circuit protection rather than schemes that require short-time selectivity or earth-fault protection.

• Main incomer or outgoing feeder protection in LV main and sub-distribution boards.
• Three-phase, three-wire circuits without a switched neutral (3P3d).
• Where short-time discrimination between breakers is required, a Micrologic 5.0 (LSI) unit is needed instead.
• Where earth-fault protection is required, a Micrologic 6.0 (LSIG) unit is needed instead.
• Where a withdrawable breaker is required, a drawout version of the NS800H is available under a different reference.

Frequently Asked Questions

What protection does the Micrologic 2.0 trip unit on the NS800H provide?

The Micrologic 2.0 trip unit provides LI protection: adjustable long-time protection against overload plus instantaneous protection against short circuit (ANSI 49 and 50). It does not provide short-time (S) selectivity or earth-fault/ground (G) protection. If your installation needs short-time discrimination between breakers, choose a Micrologic 5.0 (LSI) unit; if it needs earth-fault protection, choose a Micrologic 6.0 (LSIG) unit.

What does the H in ComPact NS800H mean, and what is its breaking capacity?

The H denotes the breaking-capacity performance class: the NS800H has an Icu of 70 kA rms at 415 VAC. Within the same 800A frame, the NS800N version is rated 50 kA and the NS800L version 150 kA at 415 VAC. Select the performance class to match the prospective short-circuit current at the point of installation.

Is the NS800H (33467) a fixed or drawout circuit breaker?

The 33467 is a fixed-mounting, manually operated ComPact NS800H, meaning it is bolted into the switchboard rather than racked in and out. If your design requires a withdrawable (drawout) breaker for maintenance without de-energising the busbar, a drawout version of the NS800H is available under a different catalogue reference. Contact us and we will confirm the correct drawout reference for your panel.

What does 3 poles 3d (3P3d) mean on this breaker?

3 poles 3d means the breaker has three poles with all three poles protected and tripped (three protected trip elements). It is intended for three-phase, three-wire circuits without a switched neutral. For a four-pole device that also switches the neutral, a 4P version is available as a separate reference.
