Contactors
Heavy-duty AC & DC contactors engineered for traction and locomotive switching duty.
Engineered to move India's railways
Switch-gear, control-gear and locomotive components — manufactured in Bhopal since 1980, and trusted on the line by Indian Railways, Siemens and BHEL.
Four decades of switch-gear and locomotive engineering, built on the factory floor in Bhopal.
Since 1980, Inderr Engineering has manufactured switch-gear and control-gear components and locomotive products for India's railways and the OEMs that build them. Contactors, master controllers, driver desks, panels, relays and precision fabrication — designed, made and tested under one roof.
World-class production meets genuine innovation: an ISO 9001:2015 quality system, welding certified to EN 15085-02, and a 150-strong product range refined across 30+ years in service.
