The Clipsal MAX9 MX9MC3 range of 3 Pole Circuit Breakers provides 3P miniature circuit breaker protection with a C curve and a 6kA breaking capacity. It is available in 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A and 63A ratings, so one range covers a wide spread of three-phase circuits.

Each breaker is rated 415V AC and has a compact 54mm (3 modules) DIN rail body with positive ON/OFF contact indication. The range suits MAX9 pin type busbar and MAXBAR as a main incomer, and protects against overload and short-circuit currents with top or bottom line connection.

Key Features

Q. What current ratings are available in the Clipsal MX9MC3 range?
A. The Clipsal MX9MC3 range of 3P C curve MCBs comes in 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A and 63A: 6A (MX9MC306), 10A (MX9MC310), 16A (MX9MC316), 20A (MX9MC320), 25A (MX9MC325), 32A (MX9MC332), 40A (MX9MC340), 50A (MX9MC350) and 63A (MX9MC363). Choose the variation that matches the circuit being protected.

Q. What breaking capacity and tripping curve does the Clipsal MX9MC3 range have?
A. Every breaker in the MX9MC3 range has a 6kA (6000A) breaking capacity at 415V AC and a C curve, tripping magnetically at 5 to 10 times rated current. Service breaking capacity is 100% of Icn.

Q. What cable sizes do the Clipsal MX9MC3 range terminals take?
A. All ratings use tunnel terminals for top or bottom connection with a 14mm strip length. The 6–25A ratings take 1–16mm² flexible or 1–25mm² rigid cable at 2 N.m, while the 32–63A ratings take 1–25mm² flexible or 1–35mm² rigid cable at 3.5 N.m.

Q. Can the Clipsal MX9MC3 range be used on a MAX9 PRO chassis?
A. No. Clipsal lists the MX9MC3 range as DIN rail mounted MCBs. They suit MAX9 18mm pitch pin type busbar and MAXBAR as a main incomer. For the MAX9 PRO phase and neutral chassis, Clipsal offers the MAX9 phase neutral MCBs (MX9MN range, rated 6A to 40A).

Q. What is the difference between the Clipsal MX9MC3 and MX9MC1 ranges?
A. The MX9MC3 range is 3P, rated 415V AC and 54mm wide, while the MX9MC1 range is 1P, rated 240V AC and 18mm wide. Both are 6kA, C curve MAX9 MCBs; the 1P range runs from 2A to 63A and the 3P range from 6A to 63A.
