B, C and D tripping characteristic
B: Available with the DZ47 series has rated currents of 1 through 63 amperes in 10 steps. The "B" time-current curve is designed primarily for use in cable protection applications. Instantaneous tripping occurs between approximately 3 to 5 times rated current in 50/60Hz systems. This quick trip curve maximizes protection of control circuits under low short circuit fault levels that could damage control wiring.
For protection of Resistive loads such as bulbs, heaters etc, generally suitable for domestic applications. They may also be used in light commercial applications.
C: Available in the DZ47-63 series with rated currents up through 63 amperes. The "C" time-current curve is designed for medium magnetic start-up currents. Instantaneous tripping occurs between 5 and 10 times rated current in 50/60 Hz systems. The ‘’C’’ characteristic is also available in other DZ47 series MCBs.
For protection of Inductive loads such as motors, air conditioners etc devices are the normal choice for commercial and industrial applications.
D: The new magnetic trip action has an instantaneous trip point of approximately 15 times the breaker rating. Thus, the DZ47-D can be a good protective solution for applications involving high in-rush transformers, motors and other high inductive systems. The DZ47-D is also suitable for any application where a high instantaneous trip point is desired. Available in the DZ47 series.
For protection of Cables and highly inductive loads which have high starting current such as examples include large battery charging systems, winding motors, transformers, X-ray machines and some types of discharge lighting.
Application:
• Convenience receptacle circuits (internal / external)
• Motor control circuits
• Load circuits leaving the equipment (external)
• HACR equipment (Heating, Air Conditioning, Refrigeration)
• PLC I/O points
• Computers
• Power supplies
• Control instrumentation
• Relays
• UPS
• Power conditioners
