EATON FAZ-D25/3-NA IEC Miniature Circuit Breaker, 25 A, 48/96 VDC, 10kA at 277/480 VAC, Screw Clamp, D

Eaton FAZ-D25/3-NA miniature circuit breaker (MCB) is used for protection from medium-level short circuit faults, such as in lighting, coils & control panels.

Features:

• It features a thermal-magnetic trip to provide both long-time and instantaneous current limiting protection.
• This circuit breaker has a 25A standard current rating and a maximum interrupting capacity of 10kAIC at 277 / 480V AC.
• It can accommodate wire sizes ranging from 18 to 6 AWG.
• This C-curve circuit breaker comes equipped with a toggle actuator for manual action.
• It provides DIN rail mounting to minimise installation & wiring downtime.

Standards and Approvals:

• UL
• RoHS
• CSA
• IEC 60947-2

Frequently Asked Questions:

Q. What is the operating temperature range of Eaton FAZ-D25/3-NA miniature circuit breaker?

A. This circuit breaker can be operated at temperatures ranging from -4 to 140 degrees F.

Q. What is the difference between MCCBs and MCBs?

A.

• MCBs protect items from current overloads while MCCBs protect equipment from fault currents & excess temperature rise.
• The tripping circuit of MCBs is fixed while MCCBs have a movable tripping circuit.
• MCBs have comparatively low interrupting ratings than MCCBs.

Q. Which type of terminal connection is used in this circuit breaker?

A. This circuit breaker uses a screw clamp connection.

Q. What causes miniature circuit breakers to trip?

A. Overloading a circuit is the primary reason for frequent short-circuit tripping.
