Product Positioning

The 3RT2024-1BP40 is a 230V DC coil version, officially positioned as an electrically and form factor compatible replacement for the discontinued 3RT1024-1BP40. It shares the same dimensions and contact configuration, allowing for direct reuse of existing wiring harnesses and external contacts. The main circuit maintains AC-3 12A, 5.5kW/400V, with an operating temperature range of -25°C to 60°C. It is suitable for production lines and electromechanical upgrade projects that require continuity of existing 230V DC control circuits or where equipment is located in areas with large temperature variations.

Core Product Advantages and Features
230V DC coil continues the design of the old model
Electrically and dimensionally compatible with the discontinued 3RT1024-1BP40, existing wiring designs can be reused for the replacement of older equipment.
Operates in a wide temperature range of -25°C to 60°C
It can be installed in outdoor distribution boxes or non-air-conditioned machine rooms where there are large temperature differences, and its environmental adaptability is better than that of general indoor contacts.
1NO+1NC feedback contact
It has a built-in set of normally open and normally closed auxiliary contacts, which allows the control system to monitor the engagement status of the main contacts in real time.
Multiple countries have verified and endorsed it.
It has CCC, CSA, EAC, UL and other certifications, and can meet the needs of cross-regional shipments and whole-machine verification.
