Listed as a Multi-Range Timer, the unit provides timing in the 0–99.99 second range, enabling short-delay sequencing in automation tasks. The model number 335B-351-A-10-PX identifies a 120 VAC-powered device found in distributor catalogs; multiple listings confirm a 120 VAC input. Current status across major distributors indicates the model has been discontinued by the manufacturer, which affects availability though remaining stock and refurbishers may still supply units. As a compact timer/counter, this ATC part is cataloged alongside other Automatic Timing & Controls products under the Marsh Bellofram ATC brand. Verified listings from Electrol Supply and distributor pages corroborate the 0–99.99 second timing window and the 120 VAC requirement, while third-party retailers show the exact model number 335B351A10PX with the 120 VAC indication. With its fixed timing window and industry-standard input voltage, the 335B-351-A-10-PX is suitable for applications requiring a concise time delay in control circuits and sequencing tasks, provided stock is available and compatibility is confirmed with the broader ATC/MARSH BELLOFRAM product family.
