MCB Trip Curves B / C / D
Choose the trip curve by start-up / inrush current — not by rated current alone. TIMELEC MCBs are available in B, C and D curves for domestic, commercial and industrial distribution.
Type B Curve MCB
More sensitive — for low-inrush loads
Type B is more sensitive and suits loads with small start-up surge, such as lighting, electric heating, general socket outlets, and purely resistive loads.
Type C Curve MCB
Most common — for general motor loads
Type C suits small motors, pumps, fans, air conditioners, and general industrial equipment, and is the most common choice for residential and commercial distribution.
Type D Curve MCB
High inrush tolerance — for heavy start-up loads
Type D is suitable for motors with very large start-up current, high-power transformers, welding machines, large compressors, and other high-inrush industrial equipment.

MCB Manufacturer FAQ
Common questions about TIMELEC miniature circuit breakers.
What is an MCB used for?
An MCB (miniature circuit breaker) provides overload and short-circuit protection in low-voltage AC power distribution. TIMELEC MCBs are used in residential, commercial and industrial panels to protect and control final and sub-distribution circuits.
Which standards do TIMELEC MCBs comply with?
TIMELEC miniature circuit breakers are designed in accordance with IEC 60898-1 for household and similar installations and IEC 60947-2 for industrial low-voltage circuit-breaker applications.
What current ratings and breaking capacities are available?
TIMELEC MCB ranges typically cover common distribution needs from about 1A up to 125A (series dependent), with B/C/D trip curves and 4.5kA / 6kA / 10kA breaking capacity options.
What is the difference between Type B, C and D MCB trip curves?
Type B (about 3–5 × In) suits low-inrush loads such as lighting and heating. Type C (about 5–10 × In) is the most common choice for small motors, pumps, fans and general distribution. Type D (about 10–20 × In) is for high-inrush loads such as large motors, transformers, welding machines and compressors.
Do you offer OEM / ODM as an MCB manufacturer?
Yes. TIMELEC supports OEM/ODM customization for MCB products, including ratings, poles, packaging and private-label branding for distributors and panel builders. TIMELEC is a professional low-voltage products factory, mainly producing MCB, RCBO, MCCB, AFDD, RCCB, distribution boxes, cabinets, and more.
