Eaton 2-Pole MCB, 16A Current Rating, B Curve - FAZ Series - 278734 FAZ-B16/2

Features & Benefits

• Needs only a small mounting width per pole of 17.5mm for maximum packing efficiency on a DIN rail

• Nylon housing resists corrosion, so is compatible with moist operating conditions

• Easy trouble-shooting, thanks to its colour-coded status indicator

• Captive screw terminals to help reduce the chance of screws being lost when they're unfastened

What's the difference between a B-curve and a C-curve circuit breaker?

A B-curve breaker like this one is suitable for tripping small current surges, reacting at 3 to 5 times its rated current. A C-curve device safeguards against larger surges and trips at 5 to 10 the current rating.

Eaton FAZ Series Circuit Breakers

The FAZ series by Eaton offers a wide range of quality, highly reliable and safe circuit breakers. Eaton’s FAZ DIN rail mountable circuit breaker is designed for use in control panel applications.

Features and Benefits

• The Eaton miniature circuit breaker has a current limiting design, providing short circuit interruption to reduce let-through energy, which can damage the circuit.

• Rated currents up to 63A.

• The toggle can be sealed in both the on and off position where required, and the trip-free design means that the breaker cannot be defeated by holding the handle in the on position.

• Reliable and safe operation with six levels of thermal-magnetic over-current protection.

• Red or green light indicates the contact position.

• Easy installation.

• Suitable for supplementary protection.
