If you are looking for the schematic of a 24V 11A power supply circuit rather than the relay itself, these documents provide similar high-current designs:
Introduction The phrase “f4901 11a 24v schematic free” reads like a fragment of modern technical culture: an alphanumeric key, a current or version mark, a voltage spec, and the eternal search for schematics without cost. Behind it lies a story about how knowledge, commerce, community, and repair intersect in the age of networked devices. This treatise examines that story—its technical roots, social implications, legal and ethical tensions, and the larger meaning of openness in a fragile material world. f4901 11a 24v schematic free

If you are trying to repair a broken unit, be aware that these are sealed units for safety reasons. If the internal trip mechanism has failed, the unit must be replaced rather than repaired. There are no user-serviceable parts inside a circuit breaker.
