The railway industry is known for very extreme working conditions for electrical equipment, where vibration, dust, temperature, humidity variations and electric interference requires that all electrical components must work under very harsh conditions. With a heavy demand on reliability Mors Smitt railway components are manufactured and tested to offer long effective hours of work and low life-cycle costs.
Mors Smitt offers a wide range of railway hydraulic magnetic circuit breakers. The circuit breakers are fully configurable to meet individual requirements.
New built or retro-fit, Mors Smitt delivers a perfect, competitive and on time solution for any onboard challenge of space limitations and / or technical requirements. No matter the size or quantities. We understand the need for integrated specialised and optimised electrical solutions when (spare) parts are no longer available or improvement in e.g. energy efficiency or reduction of weight and space is required.
The international railway markets demand focus on minimizing carbon footprints. Diminishing natural resources, raising energy costs, protection of the environment, de-regulation of train network traffic requires responsible and pro-active developments in the railway business.
The Mors Smitt transducers are used to measure high currents in rolling stock and trackside applications. High currents are converted linearly to low power signals.
To minimize Life Cycle Cost of products and systems it is important to perform maintenance at exactly the right moment: not too early when the product has enough remaining lifetime and not too late when the lifetime is over. Mors Smitt offers a comprehensive set of maintenance and test equipment for in-service inspection, fault finding, and verification of relay conditions for optimum Life Cycle Cost.
Mors Smitt manufacture the full range of British Rail equivalent relays including AC & DC coils, instantaneous, gold contacts, safety critical, push to test relay button, timer/time delay, and flashing.
From rail passenger cars and locomotive control and starting circuits to earth moving equipment, Vapor relays and contactors have established a reputation for quality and reliability where dependable control of DC circuits is required. Performance-proven in thousands of applications worldwide, Vapor relays and contactors meet or exceed stringent qualification requirements of major locomotive and rail passenger car builders and heavy machinery manufacturers. Units are in daily service on U.S. Class 1 railroads, the New York City Transit Authority, the Chicago Transit Authority, the Toronto Transit Commission and other railroads and transit agencies around the globe.
An Instantaneous Relay is one in which there is no time delay provided intentionally. As the current coil is an inductor, there would be a certain delay to reach the current in the coil to its maximum value.
A Timer Relay is a combination of an electromechanical output relay and a control circuit. The contacts will open or close before or after a pre-selected, timed interval.
A latching relay is a two-position electrically-actuated switch. It maintains either contact position indefinitely without power applied to the coil. It is controlled by two momentary-acting switches or sensors, one that 'sets' the relay, and the other 'resets' the relay. The latching relay maintains its position after the actuating switch has been released, so it performs a basic memory function.
A Monitoring Relay is a protective control device. The basic functions are to receive input signals, monitor and determine them, and output an alarm signal if a set value (threshold) is reached. Monitoring Relays monitor power supplies (voltage, current, power, phase), temperatures, and other analog signals and detects abnormalities in machines and equipment by determining values against alarm thresholds.
