The Mitsubishi Electric CP30-BA is a circuit protector (circuit breaker for equipment) to IEC 60934 for supplementary protection of control circuits in equipment and control panels. It is available in 1P, 2P and 3P with rated currents from 0.1 A to 30 A.

What is a Mitsubishi circuit protector?

• A circuit breaker for equipment to IEC 60934, used for supplementary and control-circuit protection.
• It does not replace an MCCB for branch-circuit protection.

Which CP30-BA ratings are available?

• Frame: 30 A; poles: 1P, 2P, 3P.
• Rated current: 0.1, 0.25, 0.3, 0.5, 1, 2, 3, 5, 7, 10, 15, 20 and 30 A.
• Spring-clamp terminal version: 0.1 A to 20 A.

What are the CP30-BA's main specifications?

• AC/DC common for 1P and 2P (AC 250 V; DC 65 V for 1P, DC 125 V for 2P per UL 1077); 3P is AC only.
• Breaking capacity 2.5 kA (IEC 60934 Icn at AC 230 V; IEC 60947-2 Icu/Ics 2.5/2.5 kA).
• 17.5 mm width per pole.
• Reverse connection allowed; line and load sides are not defined.
• Open/close compact terminal cover as standard, IP20 from the front.

Which trip characteristics can I choose?

• Instantaneous (I), electromagnetic trip.
• Medium-speed (M) and medium-speed with inertial delay (MD).
• Slow (S) and slow with inertial delay (SD).
• High-speed (F).
• All types other than I use a hydraulic-magnetic trip.

How is the CP30-BA mounted and wired?

• Terminals: screw, tab or spring-clamp.
• Mounting: surface, IEC 35 mm rail or flush (FP).
• Internal accessories: AL alarm switch, AX auxiliary switch and SHT shunt trip (relay type).

Which standards does the CP30-BA meet?

• IEC/EN 60934 and IEC/EN 60947-2.
• UL 1077 / CSA C22.2 No.235 (cURus recognized).
• CCC, CE and UKCA.
