The Circuit Breaker FEC 88 series provides current ratings ranging from 6A to 63A (6A, 10A, 16A, 20A, 32A, 40A, 50A, and 63A) across all pole types, accommodating diverse circuit loads from standard lighting and power points to heavy-duty equipment.
The Circuit Breaker is Operating at 240V for 1P and 2P models, and 415V for 3P units at 50Hz frequency, these breakers deliver a rated breaking capacity of 6kA.
The Circuit Breaker is Featuring B/C tripping characteristics for 1-pole units and C-curve tripping characteristics for 2-pole and 3-pole models, they effectively manage moderate inrush currents typical of inductive and resistive loads.
Designed for standard DIN-rail mounting inside consumer units and distribution boards, each MCB features color-coded current indicators for clear visual identification during maintenance and routine inspections.
Once installed inside an enclosure, the units maintain an IP40 degree of protection to guard against ingress of solid objects.
Whether specifying for residential property wiring or commercial DB board upgrades, the Crown FEC 88 series provides standard-compliant circuit protection and reliable performance across everyday power networks.

Frequently Asked Questions (FAQ)
-
Q: What does the 6kA breaking capacity mean on the Crown FEC 88 MCB?
A: Breaking capacity (6kA) refers to the maximum short-circuit current that the MCB can safely interrupt without causing permanent damage to the device or electrical installation.
-
Q: What is the difference between 1 Pole, 2 Pole, and 3 Pole MCBs?
A: 1-Pole MCBs protect a single active line (single-phase circuits, like basic lights/power points). 2-Pole MCBs protect both active and neutral lines. 3-Pole MCBs are designed for 3-phase electrical systems (415V), commonly used in commercial buildings or heavy machinery.
-
Q: Why are there different handle/marker colours for each amp rating?
A: The colour coding (e.g., Blue for 16A, Yellow for 20A, Red for 32A) allows electrician maintenance teams to instantly recognize current ratings during installation and troubleshooting inside distribution boards.
-
Q: What tripping characteristic curves do these MCBs have?
A: The 1-Pole models are available with B/C characteristics, while the 2-Pole and 3-Pole models feature C-curve characteristics, making them suitable for handling general electrical loads and moderate inductive currents.
-
Q: What does the IP40 protection rating signify?
A: An IP40 rating indicates protection against solid objects larger than 1mm once the MCBs are mounted inside an electrical distribution board or consumer box.
