RCBO Residual Circuit Breaker Overload

FEATURES

- Our RCBO range uses AC residual current, and trip levels are typically between 30mA, 100mA and 300mA

- A range of various trip characteristics are available: instantaneous fixed time delay and inverse time delay

- Fitted with a ‘test button’ to check the circuit breakers trip setting when an appropriate residual current fault is generated internally

- Electrical connections to the unit are via M6 terminals, auxiliary contacts can be used to control and monitor the state of the circuit breaker

2 POLE SERIES 373 & 4 POLE SERIES 368

The circuit uses a current transformer to measure AC current imbalance.

The signal is amplified, rectified and then passed to a time delay circuit. If the signal is present after the delay then a solid state switch energises the supply circuit breaker trip coil.

Options for either a fixed time delay or an inverse time delay trip characteristics can be specified. Trip currents can be specified for factory setting at levels between 5 and 300mA (Trips levels up to 2A are possible on a 4 pole series). A unit with a trip level of 5mA is specifically suited for the American market to meet the requirements of the ‘National Electrical Code NFPA 70’.

A wide range of time delays can be specified and set during manufacture. The detector circuit power supply is derived from the ac supply.

A test signal can be injected through the current transformer from a test button to confirm correct operation.

BENEFITS

Tripping characteristics:

- Inverse time curve – the operating time of the RCBO is reduced as the residual current increases

- Fived time delay – the units are tolerant of traction auxiliary supply functions

4 POLE DIMENSIONS

2 POLE DIMENSIONS

Designed for harsh environments – industrial and rail traction – the Rowe Hankins RCBO uses the industry proven Eaton® AMR series circuit breaker with an integrated current sensor.

Speed Sensors

For most applications the speed sensors are designed to work against a ferromagnetic steel target wheel by using Hall Effect sensor technology.

Sensors can however be designed for magnetic target wheels with alternating north & south poles. Operating air air gap can be up to 4mm but is determined by type of sensor and target wheel profile which for ferromagnetic targets are typically a spur gear profile.

The speed sensor can have single, dual or multiple output channels of which specific channel(s) can be isolated to be powered from a different power supply. Output channel drive circuits are available as open collector, supply tracking, push-pull or 2-wire. See table opposite for generic technical details.

Connecting screened cable and connectors are selected to meet customer requirements as well as relevant fire & smoke certification.

NIC

FEATURES

- Non-contact measurement of dc currents up to ±600mA

- 4 to 20mA current output

- Current Trip with relay output

- LED trip indicator

- 24V DC power supply

- Supply Reverse Polarity protection

- DIN rail mounting

- Unipolar versions also available

- Network Rail Approved

For trackside application to assist Network Rail’s preventative maintenance program, monitoring currents (AC and DC) in rail signalling equipment for potential problems so repairs are done prior to significant failure and rail service delays.

The NIC is used as part of the preventative maintenance systems on trackside applications. If the signal received from the NIC via the associated data logger to the programme output highlights the primary current variations are outside the normal limits, then it indicates there is a potential problem.

This is done when the cable carrying the current to be monitored is passed through the hole in the side of the case. Internally it passes through a current transducer which outputs a voltage to the rectifier stage. Following full wave rectification the signal passes through a low pass filter, the output of which connects to the 4 to 20mA current output stage. (Note the full way rectification only applies to units for bipolar primary input current).

A comparator detects a desired trip level and the output is available as a relay contact output. An internal power supply is used to convert the 24V dc supply input to power the transducer and signal conditioning circuits.

BENEFITS

- Enables significant reduction in manual routine inspection

- Ability to ‘fix before failure’

- Network Rail and SNCF approved

- Intelligent Infrastructure initiative for remote condition monitoring and proactive maintenance

iWFL Intelligent Wheel Flange Lubrication

Distribution Products for Rail

To extend rail and wheel life by geographical location based dispensing of flange lubricants and top of rail friction modifiers with IWFL. IWFL is an on-board system dispensing system.

The IWFL system is a depot refillable wheel/rail interface friction management system. It has full approvals for railway use and can be installed within or beneath the rail vehicle. It uses minimal amounts of flange lubricant and, if required, top of rail friction modifier. The use of programmable dispense volumes combined with network location based dispensing allows many trackside lubricators to be removed.

We work with the client to provide the optimum iWFL design combination.
