The Mitsubishi CP30-BA1P1M5A is a single-pole, 5A miniature circuit breaker from Mitsubishi Electric's WS-V (World Super V) series. This UL 1077 certified circuit protector is specifically designed for protecting individual load circuits, control circuits, and branch circuits within industrial control panels and machine enclosures.

The WS-V series is engineered to meet the demanding requirements of panel builders across global markets. With comprehensive multi-certification (UL 1077, IEC 60947-2, CSA, TÜV, CE), the same catalog number can be used for panels destined for North American, European, and Asian markets, simplifying global machine compliance.

The series features improved short circuit interruption capability and consistent trip characteristics, providing reliable protection with a 2.5 kA breaking capacity at 250V AC under UL 1077 conditions.

The M-curve (medium-speed) tripping characteristic is ideal for circuits with moderate inrush currents, making it suitable for:

• Relay coil circuits
• Small motor starters
• Solenoid valves
• 24V/48V DC power supply outputs
• Automation control loads

This curve provides protection against sustained overcurrent while tolerating normal startup transients without nuisance tripping.

The 65V DC voltage rating makes this protector ideal for 24V and 48V DC control circuits commonly found in:

• PLC I/O power distribution
• Fieldbus power supplies
• Servo drive control power circuits
• HMI supply lines

The device is specifically rated for DC fault interruption, ensuring proper protection in DC control systems.

Screw-clamp terminals provide reliable, re-tightenable connections suitable for industrial environments with vibration and thermal cycling. Standard 35mm DIN rail mounting ensures easy integration into control panels alongside other protection devices.
