ABB AIBP-51 68257913 Protection Board Kit

Applicable input voltage range: 380-550V AC (three-phase industrial voltage), supports ±10% fluctuation compensation;

Rated continuous working current: 50A, peak current tolerance up to 200A (for 5 seconds);

Response time: overcurrent protection response <100μs, overvoltage protection action voltage threshold is configurable (typical value 600V AC).

Dimensions: compact design suitable for standard 35mm rail installation;

Weight: lightweight metal housing (galvanized steel plate), surface sprayed with moisture-proof and anti-corrosion coating.

Operating temperature range: -20°C~+70°C (no cooling fan, natural convection cooling);

Protection level: IP20
Anti-electromagnetic interference: complies with IEC 61000-6-2 industrial electromagnetic compatibility standard, and can resist high-frequency harmonics and radio frequency interference.

ABB AIBP-51 adopts a combination of "metal oxide varistor (MOV) + ​​fast fuse", which can absorb surge energy (maximum 6kV/3kA surge) and physically cut off the circuit within 0.1ms when short-circuited to prevent the main module of the inverter from burning.

The built-in voltage sensor monitors the input waveform in real time, and outputs an alarm signal (dry contact output) through the relay contact when abnormal.

ABB AIBP-51 does not require additional wiring or configuration software, and is directly connected to the inverter through the ABB dedicated interface, shortening the installation time by more than 50%;

Supports hot swapping (power off operation), and there is no need to shut down the entire system for maintenance. Only the module can be replaced to resume operation.

Front-end 4-color LED indicator displays status in real time (green: normal power supply; yellow: overload warning; red: fault tripping; blue: communication connection);

Integrated Modbus RTU communication interface, can be connected to ABB Ability™ digital platform, remote monitoring protection module working status, fault history and remaining life prediction.

Key components use military-grade impact-resistant devices and pass 100,000 life tests;

ABB AIBP-51 supports dual-channel DC power input (12-24V DC redundant power supply) to avoid single-point power failure causing protection failure.

Inverter Protection: In ABB drive systems of wind turbines, photovoltaic inverters, and pumped storage power stations, it protects against damage to the input bridge caused by lightning strikes, closing surges, and voltage drops in the power grid;

Substation Automation: Cooperate with ABB relay protection devices to protect medium and low voltage distribution cabinets from overcurrent, and improve the stability of the power system.

Petrochemical and Chemical Industry: Applied in reactor stirring motors and delivery pump inverters, adapting to high temperature and highly corrosive environments, and reducing unplanned downtime;

Metallurgy and Papermaking: Ensure the stable operation of the drive system of continuous production equipment such as continuous casting machines and papermaking machines, and avoid process interruptions or product quality defects caused by power supply fluctuations.

Water Treatment System: Protect the inverters of sewage lifting pumps and aeration fans, and support long-term operation in humid and dusty pump room environments;

Smart Building and Energy Management: Integrated with ABB building automation systems, it provides power protection for central air-conditioning chillers and elevator drive systems, and optimizes equipment life cycle costs.
