A relay assembly comprises a vital relay used in a vital circuit and configured to be rack-installed in an equipment room in a railroad case or a railroad housing for providing a modular solid-state current-limiting. The relay assembly further comprises a plurality of vital relay contacts to which a current flow is restricted by a single supply solid-state current limiter. The relay assembly further comprises a relay socket base assembly coupled to the vital relay. The relay socket base assembly includes a relay socket base including a plurality of vital relay contact prongs, a plug assembly including a plurality of printed circuit board (PCB) mounted contact terminals, and a plurality of contact terminals that provide a connection between the plurality of vital relay contact prongs and the plurality of printed circuit board (PCB) mounted contact terminals. The relay assembly further comprises an ancillary electrical control module.

A novel electrical box to house one or more ISO micro relays, is adapted to support IP67 and IP69K Ingress Protection ratings. The housing of the electrical box is molded with blade sockets that correspond to blade positions of the ISO micro relay. The housing is also molded with terminal seats and cylindrical openings which vary, depending on the blade socket, enabling terminals of different sizes, orientations, and positions relative to the respective blades, to be easily inserted into the back of the housing. The resulting position of the terminals ensures that electrical connections to the ISO micro relay are made and ingress protection of components inside the electrical box is ensured.
